Think Smart, Build Secure

LiWiR’s Agile Classical Cryptographic Solutions

Classical cryptographic solutions is an umbrella term encompassing almost all
cryptographic algorithms in place today. The term is juxtaposed with post-quantum
solutions which are currently being standardized to combat the looming threat that
quantum computers pose. Even with access to large scale quantum computers,
many classical solutions are still safe and secure. Additionally, we realize the
transition to a quantum-safe system is a long and complex process that can be
expensive for companies. Therefore, LiWiR offers a wide array of agile classical
solutions to fit the needs of all companies.

Private-key (Symmetric) Cryptography

Private-key, or symmetric, cryptography refers to a class of algorithms that use the
same key for encrypting and decrypting information. These algorithms are not
considered “broken” in the quantum setting. However, to keep using the same
algorithms at the same security level, we must double the key sizes to remain
secure.These algorithms include the Advanced Encryption Algorithm (AES) and the Secure
Hash Algorithm (SHA), both of which have been standardized and are offered by
LiWiR.

Public-Key (Asymmetric) Cryptography

Public-key, or asymmetric, cryptography refers to a class of algorithms that require a
different key for encryption and decryption. These algorithms traditionally have a
public-key private key pair (hence the name) where the public-key is shared over a
public channel and then combined with a private key to produce a shared secret key.
This shared secret key is typically used as the key for private-key cryptography. In the
quantum setting, all standardized classical public-key cryptography is considered
“broken” and needs to be replaced by quantum-safe solutions. However, at LiWiR we
understand each company has their own goals and time frames and thus we are
here to assist in all of their cryptographic needs.These algorithms include RSA and variants of elliptic curve cryptography (ECC).
LiWiR offers a wide range of hardware solutions and software solutions for every
need from high-end servers to low-end embedded devices. For more information on

Problems

• Increasing demand for speed of computation and low energy consuming secure communication alorithms

• Importance of data security in smart and financial applications in almost every sector

• Need for lightweight secure, attack resistant and fast crypto algorithms.

• Lack of small and single pass Authenticated Encryption with Assoicated Data (AEAD) for the highly recource restricted devices.

• Due to the variability of applications and requirements, hard to select a one-size-fits-all algorithm.

Solutions

• Permutation based AEAD lightweight ciphers enhance latency, throughout efficiency with less hardware foot print using due advantage of the single-pass encryption and authentication scheme proposed for pervasive devices

• Ensure security and privacy in the IOT applications

• Optimized latency and energy consumtion by the lightweight devices Ex: RFID tags, smart cards

Internet of Things (IoT)

The world is now more connected than ever before. Critical devices – including some
that we never imagined would be remotely controlled – are now a part of a massive
network of technologies. This network is not isolated: it is part of the internet. And
what could go wrong on the internet…?Security is not a luxury when it comes to medical devices that transmit sensitive
personal information, our connected homes, or the energy infrastructure and smart
cities we rely on.The software and hardware revolutionising every aspect of modern life must also meet
minimum security requirements and follow cybersecurity best practice.Whether it’s for long-lasting confidentiality reasons, or for devices with long lifespans,
the ‘security by design’ approach requires us to be ready for tomorrow’s challenges,
today.
